Description

technical field

[0001] The invention relates to the Ethernet passive optical network technology, in particular to a multicast service authority control method of the Ethernet passive optical network, an optical network unit and an optical line terminal. Background technique

[0002] EPON (Ethernet Passive Optical Network, Ethernet Passive Optical Network) technology is an emerging Ethernet-based broadband passive optical network technology. It is essentially an extension of Ethernet in the field of access networks. The structure of the EPON system is as shown in Figure 1, including OLT (OpticalLine Terminal, optical line terminal) 11, optical splitter 12 and ONU (OpticalNetwork Unit, optical network unit) 13, the PON mouth of an OLT 11 can pass optical branch The device 12 is connected to a plurality of ONUs 13. The downlink data transmission method from the OLT to the ONU is generally a time-division multiplexed physical layer broadcast method, that is, each downlink fram...
